Özet
Formant frequency of vowels in a language is considered as one of the
important acoustical parameter of speech signal. This parameter can be
seen as acoustic resonance of human vocal tract. Although formant
frequencies which is changeable across genders, age, and languages have
been studied for various purposes by many researchers in some languages,
alteration effects of stop consonants on adjacent vowels hasn’t been
worked yet for Turkish language. In this study, formant frequency values
(F1, F2 and F3) of eight isolated vowels (/a/, /e/, /ı/, /i/, /o/, /ö/, /u/, /ü/)
have been compared to formant frequency values of vowels that come after
any stop consonant (/p/, /t/, /k/, /b/, /d/, /g/) to detect any changes caused
by stop consonants in formant frequencies. Totally 48 meaningful Turkish
syllables (combinations of all stop consonants and all vowels) and 8
isolated vowels have been uttered by 10 male speakers three times
repeatedly for each unit. At the end of this study, the plosive stop
consonants /p/ and /g/ among others have been found as the ones having
most alteration effects on F1 value of adjacent vowel /a/ in a CVC-context
syllable. F2 of isolated vowel /a/ has been shifted up with /k/ and /g/ visibly.
Also, F3 of /a/ has been shifted down by approximately 150 Hz with the
same plossive stop consonants /k/ and /g/. These findings can help
researchers studying on formant frequencies of vowels in Turkish language
in order to specify right syllables to deal with
